====== The Basics: Exercise 1 ======

Create an aspect named ''Basics'' with an auxiliary method ''output'':

<code aspectj>
public aspect Basics {

  public void output(String tag, Object o) {
    System.out.println(tag + ": " + o);
  }

}
</code>

Next, add an advice to this aspect to prints a string just before the execution of the ''start()'' method. Use the following form for your advice:

<code aspectj>
before(): <pointcut> {
  output("ex1","About to start");
}
</code>

<note tip>
You can employ the primitive pointcut ''execution(//Signature//)''. The signature pattern should at least specify the return type, the method name and the arguments.
</note>

Rerun the application to see the output from your aspect.
